Security in WLAN

Abstract

The great promise of wireless LAN will never be realized unless there is an appropriate security level. From this point of view, various security protocols have been proposed to handle wireless local-area network (WLAN) security problems that are mostly due to the lack of physical protection in WLAN or because of the transmission on the radio link. The purpose of this chapter is (1) to provide the reader with a sample background in WLAN technologies and standards, (2) to give the reader a solid grounding in common security concepts and technologies, and (3) to identify the threats and vulnerabilities of WLAN communications.
